Abstract

The invention relates to the technical field of spaceflight, in particular to an unfolding device of a solar cell array. The unfolding device of the solar cell array mainly comprises a connecting bottom plate, a driving device, a support and a tensioning and releasing assembly. Wherein the connecting bottom plate is fixedly connected to a satellite body, the driving device is arranged on the connecting bottom plate, one end of the support is connected to the connecting bottom plate, and the other end of the support is connected to the driving device, so that the driving device can drive the support to rotate around the connecting bottom plate. Under the first preset condition, the tensioning and releasing assembly is connected with the moving end of the support, and under the second preset condition, the tensioning and releasing assembly is disconnected from the moving end of the support. The unfolding device of the solar cell array is simple in structure, high in response speed during unfolding and folding, capable of being repeatedly used, capable of saving cost and improving working efficiency, and high in stability and reliability.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a device for deploying a solar cell array. Background technique [0002] With the development of the economy and the advancement of science and technology, human beings have a constant yearning for the unknown world and the mysteries deep in the universe. Human beings' continuous exploration of the universe is inseparable from the application of spacecraft. However, the main energy supply in spacecraft is inseparable from solar cell arrays. Therefore, at present, human beings usually apply solar cell arrays to low-orbit small satellites to meet the energy requirements for the normal operation of low-orbit small satellites. [0003] Solar arrays on low-orbit small satellites are usually installed on the deployment device of the solar array. With the continuous increase in the power demand of low-orbit small satellites, there is an urgent need for space solar arrays with highe...
